报错图片：

这个错误的核心问题是：系统找不到ArcGIS Runtime的本地库文件。

1.问题根源分析

(1)ArcGIS Runtime Java SDK由两部分组成：

(2)Java API - 纯Java代码，通过Maven依赖引入

本地库文件 - 平台相关的本地动态库（Windows的dll、Linux的so、macOS的dylib）

错误提示表明系统在以下位置都找不到本地库文件：

通过代码设置的安装目录

当前工作目录

环境变量指定的目录

用户home目录下的.arcgis文件夹

2.解决方案

在项目目录下执行以下命令

复制代码

mvn dependency:unpack
